Abstract
The aim of this study is to search the effects of tibial torsion on flexible flatfoot. For this purpose, 20 children with flexible flatfoot and external tibial torsion were determined as a study group. The control group which consisted of 10 children with flexible flatfoot without rotational problems was included in the study. Plantar flexion angle of talus, talo-1. metatarsal angle and dorsoplantar talocalcaneal angle were measured on standing foot radiographs. Tibial torsion was measured by computed tomography. Plantar flexion angle of talus and dorsoplantar talocalcaneal angle were found significantly lower in the study group (p<0.005 and p<0.005 respectively), although talo-1. metatarsal angle was not significantly different between the groups (p=.2917). Naviculo-cuneiform sag was prominent in all cases of study group. In conclusion, abnormal external tibial torsion may affect the foot deformity and this can change the benign nature of the flexible flatfoot.
